Research Report RR:D14-1017
The precision of this test method is based on an interlaboratory study of D1002-05, Standard Test Method for Apparent Shear Strength of Single-Lap- Joint Adhesively Bonded Metal Specimens by Tension Loading (Metal-to-Metal), conducted in 2006. Eleven laboratories tested four different adhesive / substrate combinations for calculated failing load, percent adhesion to metal, and percent cohesion of adhesive. Every test result represents an individual determination. The laboratories were asked to report five replicate test results from each of two different times (a.m. and p.m.) for every adhesive / substrate combination. Following the initial data review, and internal investigations by the participants, qualified data from only five of the laboratories were utilized in determining the final precision statistics. Practice E 691 was followed for the design and analysisof the data; the details describing the distinct data populations and outliers that were identified are given in ASTM Research Report No. D14-1017.
